Hello, I'm at the stage of connecting my GA4 Data Source via BigQuery. When I test the connection it says: "We were able to connect to BigQuery, but we weren't able to retreive any datasets in this project." I can confirm all instructions were followed. I only connected BigQuery to GA4 today, which won't have pulled any Ga4 data, is this why ?

Did you just set this up? it can take a day for data to make its way to BigQuery
